[0037] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but is merely representative of the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative work shall fall within the protection scope of the present utility model.

[0039] The present utility model relates to a preferred embodiment of a tape feeding device for a zipper cloth tape of an ironing tape.

[0040] See also Figures 1 to 3 The zipper tape unwinding device for ironing tape comprises a machine base A6, a machine head A7, a vertical and horizontal flipping mechanism and a zipper tape unwinding mechanism: the machine base A6 is provided with a winding tube for winding the zipper tape, the vertical and horizontal flipping mechanism is arranged on the machine base A6 and is used to drive the winding tube to flip between a vertical state and a horizontal state, and the zipper tape unwinding mechanism is installed on the machine head A7 and is used to unwind the zipper tape wound on the winding tube.

[0041] In an exemplary embodiment, the upright and horizontal turning mechanism includes a turning cylinder A2, a turning frame A1, a lifting cylinder A4 and an upper ejector pin A5: one end of the turning cylinder A2 is hinged to the machine base A6, the piston rod at the other end of the turning cylinder A2 is hinged to the turning frame A1, the piston rod of the lifting cylinder A5 is connected to the turning frame A1, the other end of the lifting cylinder A5 is connected to a connecting plate A12, the upper ejector pin A5 is installed on the connecting plate A12, and the upper ejector pin A5 is configured to be able to support the winding tube.

[0042] Furthermore, the flip frame A1 is connected to the base A6 via an optical axis A13. The flip frame A1 is in a vertical position in an initial state. A built-in bearing A14 is provided at the connection end between the flip frame A1 and the optical axis A13 for rotatable support.

[0043] The base A6 is also provided with a blocking rod A15 and a blocking rod A16. The blocking rod A15 is configured to position the turning frame laterally, and the blocking rod A16 is configured to position the turning frame A1 vertically. The blocking rod A15 and the blocking rod A16 can ensure the stability and accuracy of the vertical and horizontal turning mechanism when turning.

[0044] Furthermore, a main transmission motor A3 for controlling the running speed of the winding tube is installed on the machine base A6, and the main transmission motor A3 is electrically connected to the main control board. Preferably, after the main transmission motor is started, the running speed of the winding tube is controlled by chain transmission to achieve continuous or intermittent release of the fabric tape.

[0045] The vertical and horizontal turning mechanism can drive the winding tube to turn between the vertical state and the horizontal state, so as to smoothly carry out the subsequent zipper tape unwinding operation. The turning process of the winding tube by the vertical and horizontal turning mechanism is as follows:

[0046] In the initial state: the winding tube wrapped with zipper tape after dyeing is placed on the base A6 of the vertical and horizontal turning mechanism. At this time, the turning frame is in a vertical state, the lifting cylinder A4 is in a non-working position, and the upper ejector A5 does not support the winding tube;

[0047] Press the switch of the vertical and horizontal flipping mechanism, first the lifting cylinder A4 is activated, the lifting cylinder A4 descends and drives the upper ejector A5 to move downward to hold the winding tube, ensuring that the winding tube will not move or fall off during the flipping process;

[0048] Press the switch again, and the flip cylinder A2 is activated. The flip cylinder A2 drives the flip frame A1 to start rotating around the rotation center. Due to the built-in bearing A14 of the flip frame A1, it can be driven by the built-in bearing A14 under the push of the flip cylinder A2 and converted from a vertical position to a horizontal position. The winding tube changes from a vertical state to a horizontal state as the built-in bearing A1 of the flip frame rotates. During this process, the lifting cylinder A4 maintains pressure on the winding tube to ensure smooth flipping.

[0049] The vertical-horizontal flipping mechanism realizes automatic switching from vertical to horizontal, driving the zipper tape winding tube to realize automatic vertical-horizontal flipping, reducing manual intervention, greatly improving production efficiency, and ensuring the stability and reliability of operation.

[0050] In an exemplary embodiment, the zipper tape unwinding mechanism includes roller 1 C1, roller 2 C2, roller 3 C3, roller 4 C4, roller 5 C5, roller 6 C6, roller 7 C7, roller 8 C8, roller 9 C9, roller 10 C10 and roller 11 C11, which are sequentially connected from the cloth input end to the cloth output end, as well as an empty tape detection component, a tape unwinding tension control component, a knot detection component, a broken tape detection component and a main control board.

[0051] Furthermore, a vertical plate A17, a cross beam A18 and a guide rod A19 are installed on the machine head A7, the roller one C1, roller three C3, roller four C4, roller six C6, roller eight C8 and roller nine C9 are installed on the cross beam A18, the roller two C2 is installed above the machine base A6, the roller five C5 and roller seven C7 are slidably installed on the vertical plate A17, and the roller ten C10 is slidably installed on the guide rod A19.

[0052] Furthermore, the roller C1 is arranged at the cloth feeding end, and the cloth feeding end is also provided with a positioning ring D1 cooperating with the roller C1. When the zipper tape is flipped to a nearly horizontal position, it will first pass through the positioning ring D1, and the positioning ring D1 ensures that the zipper tape can pass through smoothly for transmission.

[0053] Specifically, the empty tape detection component includes an empty tape positioning ring D3, an empty tape sensor B1 and an empty tape pressing cylinder A11. The empty tape sensor B1 can contact the empty tape positioning ring D3 and send out an empty tape signal. The empty tape sensor B1 is connected to the main control board signal, and the main control board is connected to the main drive motor and the empty tape pressing cylinder A11 signal.

[0054] Further, the empty tape positioning ring D3 is cooperatively arranged on the second roller C2, the empty tape sensor B1 is arranged on the side of the second roller C2, the empty tape pressing belt cylinder A11 is arranged near the fourth roller C4, the empty tape pressing belt cylinder A11 is signal-connected to the empty tape sensor B1, and the empty tape pressing belt cylinder A11 can receive the empty tape signal and press down on the zipper cloth tape.

[0055] After the above vertical and horizontal flipping mechanism drives the winding tube from vertical to horizontal, the zipper cloth tape on the winding tube is released through the first positioning ring D1, the first roller C1 and the second roller C2 in sequence, and an empty tape positioning ring D3 is arranged on the second roller C2.

[0056] When the zipper cloth tape on the winding tube is released completely, the empty tape positioning ring D3 will fall, and when falling, it touches the empty tape sensor B1. The empty tape sensor B1 generates an empty tape signal and transmits it to the main control board. The main drive motor A3 stops rotating to shut down the equipment. At the same time, the empty tape pressing belt cylinder A11 moves downward to press the zipper cloth tape to prevent it from slipping.

[0057] Specifically, the tape release tension control assembly includes a speed regulation counterweight A8 and an encoder A20:

[0058] The speed regulation counterweight A8 is connected to the fifth roller C5. The shaft of the fifth roller C5 cooperates with the encoder A20. The speed regulation counterweight A8 is slidably connected to the encoder A20 through a slider. The fifth roller C5 is slidably installed on the waist-shaped hole of the vertical plate A17. The encoder A20 is vertically arranged on one side of the vertical plate A17, and the encoder A20 is signal-connected to the main control board.

[0059] The zipper cloth tape continues to be released and continues to pass through the third roller C3, the fourth roller C4 and the fifth roller C5 in sequence. The running speed of the main drive motor A3 is controlled according to the height of the fifth roller C5. The higher the height of the fifth roller C5, the faster the speed of the main drive motor A3. The lower the height of the fifth roller C5, the slower the speed of the main drive motor A3.

[0060] The higher the height of the fifth roller C5 indicates that the tension between the fifth roller C5 and the zipper cloth tape is greater. The fifth roller C5 slides upward. The encoder A20 detects the position signal of the fifth roller C5 and sends it to the main control board. The main control board controls the main drive motor A3 to accelerate the tape release to increase the tension of the zipper cloth tape during the transmission process.

[0061] Conversely, when the height of the fifth roller C5 decreases, it indicates that the tension between the fifth roller C5 and the zipper cloth tape is smaller. The fifth roller C5 slides downward. The encoder A20 detects the position signal of the fifth roller C5 and sends it to the main control board. The main control board controls the main drive motor A3 to decelerate the tape release to reduce the tension of the zipper cloth tape during the transmission process.

[0062] The speed-regulating counterweight A8 on the roller five C5 can achieve counterweight control to release the tape tension. The counterweight applies a constant pulling force to the tape release through its weight, which helps to maintain the tension stability.

[0063] When the zipper fabric tape is pulled out quickly, the counterweight will provide a certain resistance to prevent the zipper fabric tape from loosening due to excessive speed; when the zipper fabric tape is pulled out slowly, the counterweight ensures that the zipper fabric tape will not pile up or break due to excessive slowness. By adjusting the weight or position of the counterweight, the tension during the tape release process can be precisely controlled.

[0064] Through the above tape release tension control, the tension during the tape release process can be precisely controlled, and constant tension control during the zipper fabric tape release process can be achieved.

[0065] Furthermore, a sliding track A21 is provided on the vertical plate A17, and the roller seven C7 is slidably mounted on the sliding track A21, and the sliding track A21 is used in cooperation with the guide rod A19.

[0066] Even further, the knotting detection component includes a knotting sensor B2 and a knotting speed-regulating counterweight A10 provided on the roller ten C10. The knotting speed-regulating counterweight A10 and the roller ten C10 move up and down along the guide rod A19 through a slider. The knotting sensor B2 is provided near the guide rod A19. The knotting sensor B2 can contact the roller ten C10 and send out a knotting signal, and the knotting sensor B2 is signal-connected to the main control board.

[0067] During the continuous unwinding process of the zipper fabric tape, the empty tape first slides through the roller seven C7, and then passes through the roller eight C8, the roller nine C9 and the roller ten C10. When the zipper fabric tape on the winding tube is knotted, the roller seven C7 is at the top, and the roller ten C10 is driven to move up synchronously. During the upward movement, the roller ten C10 will touch the knotting sensor B2, and the knotting sensor B2 generates a knotting signal and transmits it to the main control board, and the main drive motor A3 stops rotating to stop the equipment.

[0068] Specifically, the tape breakage detection component includes a tape breakage sensor B3 and a positioning ring two D2. The tape breakage sensor B3 is installed above the roller eleven C11, and the roller eleven C11 and the positioning ring two D2 are installed at the cloth outlet end. The tape breakage sensor B3 can contact the positioning ring two D2 and send out a tape breakage signal, and the tape breakage sensor B3 is signal-connected to the main control board.

[0069] During the unwinding process of the zipper fabric tape, when passing through the roller eleven C11, when the zipper fabric tape breaks, the positioning ring two D2 on the roller eleven C11 will fall, and when falling, it will touch the tape breakage sensor B3. The tape breakage sensor B3 generates a tape breakage signal and transmits it to the main control board, and the main drive motor A3 stops rotating to stop the equipment.

[0070] Through the above-mentioned tape-feeding mechanism for the zipper tape, the constant-tension adjustment control of the zipper tape can be achieved, ensuring the consistency and stability of the zipper tape transmission, improving the quality of the subsequent ironing of the zipper tape, and a set of tape-feeding mechanisms on each side can improve the production efficiency;

[0071] Equipped with a variety of induction detection structures such as empty-tape detection, knot detection, and broken-tape detection, it can automatically detect the situation of the zipper tape and stop in response when encountering faults such as empty tape, knot, and broken tape, without manual intervention and monitoring, reducing human errors and downtime, saving labor costs, and ensuring the safety and efficiency of the production site.

[0072] In an exemplary embodiment, the tape-feeding device for the ironing zipper tape may also be equipped with a water-absorbing component. The water-absorbing component is used in cooperation with the zipper tape. The water-absorbing component may include a water-absorbing port positioning ring E1 for fixing the running direction of the zipper tape and a vacuum pump. The water-absorbing port E2 on the zipper tape is communicated with the vacuum pump suction port E3 of the vacuum pump, and the excess water on the zipper tape can be sucked through the vacuum pump.

[0073] The beneficial effects of the tape-feeding device for the ironing zipper tape of the present utility model are as follows:

[0074] It can realize the automatic switching of the zipper tape winding tube from vertical to horizontal, reduce manual intervention, improve production efficiency, and ensure the stability and reliability of the operation;

[0075] It can realize the constant-tension adjustment control of the zipper tape, ensure the consistency and stability of the zipper tape transmission, improve the quality of the subsequent ironing of the zipper tape, can automatically detect the situation of the zipper tape and stop in response when encountering faults, without manual intervention and monitoring, save costs, and ensure the safety and efficiency of the production site.
